Brooke Shields, 55, Leaps From A BoatWhile Swimming In Sexy Black BathingSuit

A lot of times, Brooke Shields will post an exercise video as her #MondayMotivation, but on Aug. 3 she decided to share a video that showed off the results of her dedication to working out. The 55-year-old model/actress wore a black one-piece swimsuit in a slow-motion vid where she jumped off the side of a boat and into the ocean. Brooke got some serious air, as she raised her arms above her head and then stretched her legs out to the side, showing how incredibly long, tight and lean her body is.

“Monday mood… jumping right into the week,” Brooke captioned the video with her cheeky comment. Legendary Danish-born supermodel Helena Christensen, 51, gave her model pal props, writing in the comments, “This is one very strong, fit, beautiful body holy sh*t,” with red heart emojis. Fan @zurainzimam gushed, “Whooopeere! Looking fantastic bless you! The workouts are showing great results.”

Brooke regularly shares her workouts in Instagram videos, and allows fans to keep fit along with her. Instead of flaunting her swimsuit body on the prior Monday, she showed off how she keeps it in shape in a July 27 IG video that worked her core and sides. Brooke shared an exercise she had just learned called “The Penguin,” where she laid on her back, knees bent up in the air and feet planted She then lifted her shoulders slightly off the ground and  moved her hands and arms down to touch each ankle, engaging her abs and obliques.

Brooke wore tight black leggings and a white tank top that showed off how her fitness keeps her in such fine shape. “#MondayMotivation to get moving today! Try the penguin.  it’s harder than it seems…keep your stomach tight and work your obliques,” she wrote in the caption of the workout video. If that’s one of the exercise she uses to help keep her body looking like she’s 25 at age 55, she should be everybody’s Instagram personal trainer!
